Problems solved by technology

Although the thickness of the waterproof membrane is uniform, there are seams during construction, and there are many hidden dangers in the details. A large number of seams are easy to cause penetration
At the same time, the coiled material has high requirements on the construction environment temperature and the dryness of the base layer. Once it is broken, the self-healing ability is poor, which will lead to leakage of the building.
[0004] In recent years, non-curing rubber asphalt waterproof coatings have been greatly applied and promoted in the field of building waterproofing. However, although the non-curing asphalt coatings currently on the market have good waterproof effects, they do not have root puncture resistance, which limits range of application

Abstract

The invention belongs to the technical field of building waterproof materials, and particularly relates to a non-cured rubber asphalt waterproof coating, a preparation method thereof and a root puncture resistant waterproof material. The coating includes the following raw materials in parts by weight: 35-55 parts of petroleum asphalt, 10-25 parts of a softener, 3-8 parts of a modifier SBS, 3-5 parts of a modifier SBR, 5-20 parts of a tackifier, 5-15 parts of waste rubber powder, 10-25 parts of a filler and 0.1-1.5 parts of a root-blocking agent. The waterproof coating provided by the inventionhas the dual characteristics of water resistance and root puncture resistance, is used for planted roofs, and can greatly improve the reliability of water resistance, reduce construction and maintenance costs, prolong the waterproof service life of buildings, and reduce the load bearing pressure of the buildings; and the root puncture resistant waterproof material provided by the invention can ensure the long-term integrity of a waterproof layer, reduce the number and thickness of a waterproof system, reduce the load of the buildings and reduce the number of construction, and has superioritycompared with a current root puncture resistant waterproof system.

Description

technical field [0001] The invention belongs to the technical field of building waterproof materials, and in particular relates to a non-curing rubber asphalt waterproof coating, a preparation method thereof, and a root puncture-resistant waterproof material. Background technique [0002] The planting roof system refers to the planting surface on the top of the roof garden and the underground garage. At present, the planting roof structure has many layers, reaching nine or more layers, and the construction is relatively complicated. Because the plant root system has a strong penetrating ability, it can penetrate the roof structure layer and cause serious water leakage. Once leakage occurs, it will bring great difficulties to maintenance and cause large economic losses. . Therefore, the planted roof waterproof system is the key to success. [0003] Most of the existing planting roof waterproofing systems are mainly composed of root puncture-resistant waterproofing membrane...
